Anyone know how to resolve this ?

I was seeing the same error because my path to jmap wasn't the same as the path to the java process (i.e. targeting two different versions).
Running jmap with the full path to my JDK resolved it.

If OpenJDK is used, it requires installation of debuginfo-packages.
In Centos this works with
- sudo debuginfo-install java-1.8.0-openjdk
- or sudo yum install java-1.8.0-openjdk-debuginfo.x86_64
See - https://bugzilla.redhat.com/show_bug.cgi?id=1010786#c15 - amazon linux - install openjdk-debuginfo?
